Below is what I've collected on various small or folding shovels usable on a foraging trip.
- The NATO approved folding spade. Was made by Fiskars in Finland. Now distributed by Gerbers. Highly engineered combination of nylon and steel creates a light and strong spade. Nylon sheath included. Weight: Spade: 2 lb 4 oz, Sheath: 3 oz. At Amazon.
- The Special Forces Shovel by Cold Steel is modeled after the original Soviet Spetsnaz shovel. Wildman Steve Brill carries this in a leather sheath when he gives his foraging tours. Weight: Spade: 1 lb 10.5 oz, Sheath (without belt): 6.5 oz. At Amazon.
- Glock Entrenching Tool with Saw and Pouch. At Amazon.
